Genesis 19:26-30

But Lot’s wife, from behind him, looked back, and she became a pillar of salt.

Now Abraham got up early in the morning and went to the place where he had stood before the Lord;

and he looked down toward Sodom and Gomorrah, and toward all the land of the surrounding area; and behold, he saw the smoke of the land ascended like the smoke of a furnace.

So it came about, when God destroyed the cities of the surrounding area, that God remembered Abraham, and sent Lot out of the midst of the destruction, when He overthrew the cities in which Lot had lived. Lot and His Daughters

Now Lot went up from Zoar with his two daughters and stayed in the mountains, because he was afraid to stay in Zoar; and he stayed in a cave, he and his two daughters.
